Glitch Pokemon that can be used or seen in a battle please. Similar to the (?) Pokemon in B/W and B2/W2.
If so, is there anyway it can be caught?
Although there are a number of glitches, there are no glitch Pokémon in X and Y.
If you want to see all the glitches, then look on this page.
Hope I helped
There are no glitch Pokemon in X or Y that can be battled, but there are lots of other glitches. Source
